Is it ok, or is it not?

I think that it is okay. When you are in a new relationship it is normal to want to spend a lot of time with the other person. When I first started dating my husband over 14 years ago we spent every free moment together. And yes my mood did depend on if I got to see him that day or not. If you think it is cute and it does not bother you, then screw what your friends think. It is your relationship not theirs. They will get over it.
